Lessor and Lessee agree to have their technical experts meet with
those of Continental and the Aircraft Manufacturer during the next 60 days in a
good faith effort to establish the most appropriate methodology for achieving
the Modifications. In order to implement those Modifications, it will be
necessary for Lessor to obtain certain BFE parts and components particular to
and furnished by Continental's BFE vendors. Accordingly, to the extent so
required, Lessee undertakes to make available for purchase by Owner or Lessor,
the BFE parts and components required for the Modifications contemplated herein
and to cause the vendors of such BFE parts to furnish any necessary technical
data or information and appropriate warranties. The Modifications will also
require incorporation (by supplements to the Purchase Agreement referenced
above) of a detailed aircraft technical specification similar to that utilized
by Boeing for the construction of B737-700 aircraft for Continental. Lessee will
be responsible for obtaining the technical information required to accomplish
the Modifications.
